Hey guys, I've been playing around with STM32F334R8 Nucleo board's USART module. As a part of it, I have written a small bare-metal code to print a character and unfortunately, my code isn't working. I am seeing junk on my putty window sometimes and ...
Posted on June 17, 2018 at 12:09I'm reading data from a UART with DMA and want to write that data to an SD card (on a F722). Since the data is much longer than my buffer, I chose circular buffer for the DMA.The problem now is that I need to save the...
